Subject: Shilo's LG9 mutant is dead as a doornail over Df(3L)fz-GS1a and over fz-GF3b (confirming Shilo) as well as over Df(3L)D-1rv16; completely viable over l(3)70Da1 and over dev1; completely viable and female-fertile over Df(3L)fz-M21; and completely lethal over D3 (loD3) and D7 (loD7). It is therefore an allele of loD (presumably to be called, for the nonce, loDLG9). I haven't completely finished the counts but I just did the last count on the first vial, the numbers are large and the conclusion is solid. I haven't yet done cytology so can't eliminate the possibility that it's a very small deletion, but the genetics certainly suggest nothing of the kind. Cheers, Adelaide
